PURPOSE: To obtain a camera provided with a compact triplet type photographing lens.
CONSTITUTION: This is the camera loading a triplet lens for photographing 1 constituted of a first positive refractive-power lens, a second negative- refractive power lens and a third positive refractive-power lens in turn from an object side and provided with a diaphragm 2 arranged backward and using a 35mm roll film or a 24mm roll film. When P is defined as a Petzval's sum and D is defined as the diagonal length of a photographic picture frame, the condition of 0.41≤P.D=≤0.98 is satisfied. The longitudinal direction of the photographic picture frame is bent (3a) toward the object side. In this case, P shows the Petzval's sum of the triplet lens and D shows the diagonal length of the photographic picture frame.
